NASA-STD-5001A, NASA TECHNICAL STANDARD: STRUCTURAL DESIGN AND TEST FACTORS OF SAFETY FOR SPACEFLIGHT HARDWARE (05-AUG-2008)

NASA-STD-5001A, NASA TECHNICAL STANDARD: STRUCTURAL DESIGN AND TEST FACTORS OF SAFETY FOR SPACEFLIGHT HARDWARE (05-AUG-2008)., This standard is published by the National Aeronautics and Space Administration (NASA) to provide uniform engineering and technical requirements for processes, procedures, practices, and methods that have been endorsed as standard for NASA programs and projects, including requirements for selection, application, and design criteria of an item. This standard is approved for use by NASA Headquarters and NASA Centers, including Component Facilities. The material covered in this standard is based on the consensus judgment of a working group of structural engineers from all the NASA Centers. The group was empowered by the NASA Engineering Management Council (now the Engineering Management Board) to develop more uniform design and verification criteria to be applicable NASA wide. This activity was prompted by concerns expressed by industry and NASA program management that practices and requirements in this area vary widely among Centers, making the verification of structural adequacy difficult in cases involving multiple Centers and increasing costs to verify identical hardware under different criteria. Revision A of this standard incorporates additional design and qualification requirements for pressure vessels, pressurized structure, pressurized components, and structural softgoods, along with updates to minimum design factors for joint separation of preloaded joints.
